The result of the sum calculation “byte + byte + byte + …“ is responded by a word quantity. The Show Flash
Memory Sum command adds all 256 Kbytes of the flash memory together and provides the total sum as a word
quantity. The sum is sent to the controller, with the upper eight bits first, followed by the lower eight bits.

Calculation of the Show Flash Memory Sum Command
Checksum Calculation
The checksum byte for a series of bytes of data is calculated by adding the bytes together, dropping
the carries, and taking the two’s complement of the total sum. The Show Flash Memory Sum
command and the Show Product Information command perform the checksum calculation. The
controller must perform the same checksum operation in transmitting checksum bytes.
Example) Assume the Show Flash Memory Sum command provides the upper and lower bytes of the
sum as 0xE5 and 0xF6. To calculate the checksum for a series of 0xE5 and 0xF6:
Add the bytes together
Take the two’s complement of the sum, and that is the checksum byte.
0xE5 + 0xF6 = 0x1DB
0 − 0xDB = 0x25
0xC3
0xD4
0xA1
0xB2

For the interest of simplicity, assume the depth of the flash
memory is four locations. Then the sum of the four bytes is
calculated as:
Hence, 0x02 is first sent to the controller, followed by 0xEA.
0xA1 + 0xB2 + 0xC3 + 0xD4 = 0x02EA
